Requirements for Events Framework

To use the events framework, allocate enough disk space for event data and be familiar with the disk capacity requirements.

Database Sizing for Events

Disk space for a single event is estimated at an average of 1,500 bytes.

Caution

As the number of events increases, the increase in disk space is not a straight line. The projections below are rough estimates. Disk usage can vary in production and depends on the type of messages stored.

Number of Events	Disk Space
25 million	38GB
50 million	58GB

Data and Disk Capacity for Events

For information about the default events data retention period, database dumps with and without events data, disk compacting, and more, see Manage Data and Disk Capacity in the PCE Administration Guide.

Events Preview Runtime Setting

If you participated in the preview of Events in 18.1.0, you enabled it by configuring a setting in your PCE runtime_env.yml file.

Warning

Remove preview parameter from runtime_env.yml

Before you upgrade to the latest release, you must remove v2_auditable_events_recording_enabled:true from runtime_env.yml. Otherwise, the upgrade will not succeed.

Removing this preview parameter does not affect the ongoing recording of “organization events” records.

To remove the Events preview setting:

Edit the runtime_env.yml file and remove the line v2_auditable_events_recording_enabled :
```
v2_auditable_events_recording_enabled: true
```
If you are not participating in other previews, you can also remove the line enable_preview_features.
Save your changes.
